REGULATING DEVlCE FOR THE DISTRIBUTlNG-PIPES 0F HOT-AIR FURNACES.

SPECIFICATION forming part of Letters Patent No. 414,349, dated November5, 1889.

Application filed December 31, 1888. Serial No. 295,069. (No model.)Patented in Canada February 14, 1889, No. 30,787.

To all whom, it may concern.-

Be it known that I, THOMAS GRAHAM WAN- LESS, of the city of Toronto, inthe count-y of York, in the Province of Ontario, Canada, have invented acertain new and Improved Regulating Device for the Distributing-Pipes ofHot-Air Furnaces, (for which I have obtained a patent in Canada, No.30,787, dated February 14, 1889,) of which the following is aspecification.

'The object of the invention is to design a simple device by which thehot air may be entirely cut off from any one of the distribut ing-pipes;and it consists in the peculiar conibinations and construction andarrangement of parts, all as more fully hereinafter described andclaimed.

The drawing represents a perspective sectional View of a hot-airregisterin the floor of a room and of a distributing-pipe leading fromthe said register to the hot-air chamber of a furnace, a valve arrangedin accordance with my invention being located in the saiddistributing-pipe.

In the drawing, A represents the hot-airdistributing pipe, and B thehot-air chamber of a furnace from which the said distributing-pipeextends.

O is the register with which the distributing-pipe A connects.

D is a valve located in the distributingpipe A in proximity to thehot-air chamber B. This valve is arranged so that it may close the saiddistributing-pipe in proximity to the hot-air chamber B, and thuscompletely cut off all hot air from the said distributing-pipe. A cordor chain E is connected to the valve D at one end, and after passingaround suitranged within the distributing-pipe A and the valve Dweighted, so that it will close when not pulled upon by the cord orchain E, the opposite end being connected to a lever Gr, pivoted on thebottom of the perforated plate of the register O. A button g, projectingthrough a curved slot in the said perforated plate, enables the lever Gto be turned on its pivot, and thus either open the valve or permit itto close itself.

\Vhat I claim as my invention is 1. The combination, with thehot-airchamher, the distributing-pipe, and the register, of the pivotedvalve within said pipe inproX- imity to the hot-air chamber, the leverpivoted within the register, and the cord or chain connecting said leverwith the valve, substantially as shown and described.

2. The combination, with the hot-airchamher, the distributing-pipe, andthe register, of the weighted pivoted valve within said pipe inproximity to the hot-air chamber, the lever pivoted within the register,and the cord orchain arranged within said pipe and connecting said leverwith the valve, substantially as shown and described.

3. The combination, with the hot-air chamher, the distributing-pipe, andthe register, of the valve within said pipe in proximity to the saidchamber, the horizontal lever pivoted to the plate O of the register,the cord connecting one end of said lever with the valve and arrangedwithin the pipe, and the other end of the lever provided with a buttonworking in a slot in the register, substantially as shown and described.
